Eaton’s Z-Wave Wireless Accessory Dimmer replaces a standard switch or dimmer to provide local and remote ON/OFF/DIM/BRIGHT control. When used with Z-Wave Wireless Dimmer (RF9540-N), the device provides multi-location ON/OFF/DIM/BRIGHT control without the need for traditional 3-way wiring. You can use Eaton’s Home Automation Hub or compatible Z-Wave Controller to associate each accessory with up to (5) other Z-Wave load controlling devices.
